***What is the difference between primary and secondary radar?***
The pulses of a primary radar are variably pulse-modulated,
the pulses of a secondary radar are statically amplitude-modulated
The pulses of a primary radar are variably amplitude-modulated,
the pulses of a secondary radar are statically pulse-modulated
The primary radar is displayed on a computer screen,
the secondary radar on a radar strip
The pulses of a primary radar are reflected by the aircraft's surface,
the pulses of a secondary radar system are answered by a transponder

***When using a GPS for tracking to the next waypoint, a deviation indication is shown by a vertical bar and dots to the left and to the right of the bar.
What statement describes the correct interpretation of the display?***
The deviation of the bar from the center indicates the track error as angular distance in degrees; the scale for full deflection depends on the operating mode of the GPS.
The deviation of the bar from the center indicates the track error as angular distance in degrees; the scale for full deflection is +-10°.
The deviation of the bar from the center indicates the track error as absolute distance in NM; the scale for full deflection is +-10 NM.
The deviation of the bar from the center indicates the track error as absolute distance in NM; the scale for full deflection depends on the operating mode of the GPS.
